Expo vs Ably
Side-by-side trajectory, velocity, and editorial themes.
Extending from build-and-ship into runtime observability and CI primitives.
Expo is in active release mode — SDK 55 landed in February, SDK 56 beta is now out, and the team is filling the gaps with build-time wins (Gradle and compiler caches), new product surfaces (Expo Observe in private preview), and developer-ergo additions like GitHub sign-in. A separate thread on Expo Go's App Store posture keeps recurring, signaling continued platform-store friction.
The arc is broadening past "build and ship React Native apps" into the operational layer around them: production observability with Expo Observe, CI primitives via MCP tools and compiler caches, and authentication ergonomics. The SDK cadence remains the metronome, but the most interesting motion is happening adjacent to it — at the dev-experience and runtime-ops edges.
Expo Observe is the directional bet for 2026; expect it to exit preview tying crash, performance, and user-flow analytics directly to the EAS pipeline. On the iOS side, expect ongoing posts and a push toward Dev Client and bare workflows as the more durable distribution path, with Expo Go reserved for prototyping rather than production handoff.
Ably pivots its developer surface toward AI agents as first-class consumers
Ably's developer surface has been visibly pivoting toward AI agents over the last six weeks. The CLI hit v1.0 with structured JSON output envelopes, hint fields for self-healing agents, and unified --force semantics. Two weeks later v1.1 added `ably init`, which installs the CLI plus Agent Skills bundles directly into Claude, Cursor, Windsurf, and VS Code in one step. A new AI Transport SDK lands separately, with end-to-end tool-calling and React providers for the Vercel AI SDK.
Ably is building two integration stories in parallel — agents as CLI users (via Agent Skills) and agents as transport consumers (via the AI Transport SDK). Together they bracket the workflow: agents read live data through the SDK and operate Ably itself through the CLI. The traditional client-library stream (JS, Python, Laravel) continues at steady pace in the background, with LiveObjects formally graduating to GA on the protocol-6 update.
Expect the AI Transport SDK to add tool-call adapters for at least one more AI runtime beyond Vercel — most likely the OpenAI Agents SDK or Anthropic's Claude Agent SDK — and Agent Skills coverage to expand to additional AI clients (Cline, Aider, Continue). Watch for the LiveObjects API to surface inside the chat/AI surfaces.
